Upgrade your early C5 with headers made for its fittings

Give your early C5 a matched long tube header and X-pipe upgrade while choosing the header version with emissions fittings. These kits use 1-7/8" primaries and a 2-1/2" OEM rear connection, with a choice of Performance or GREEN cats.

SKUs: 2151H420, 2151H430

Choose the early-car header version

The emissions fittings distinguish these packages from the C5 kits supplied without them. Both kits pair the 1-7/8" headers with their matching X-pipe and join the factory-style rear exhaust. The supported range for these exact two SKUs is 1997-2000.

Plan for your engine, including later modifications

Performance cats are for naturally aspirated applications. GREEN is the catted choice here that supports forced induction. If a supercharger is already fitted or part of the plan, choose the catalyst for that completed engine rather than buying around the original factory specification.
